Answer explanation

Organize terms from highest exponent to lowest exponent.

(constant terms have an exponent of zero!)

Classify this polynomial by its degree and number of terms.

x² + 6

• Linear polynomial
• Quadratic trinomial
• Quadratic binomial
• Cubic binomial

The largest exponent which is shown in a polynomial.

• exponent
• cubic
• degree
• linear

What type of polynomials is this: 3x⁴ + 2x² + 5x ?

• monomial

• binomial

• trinomial

What is the value of the constant?
2x² + 4x − 5

• 2
• 4
• 5
• −5

Add the polynomials.
(2x + 5y) + (3x - 2y)

• 3x + 5y
• 5x + 3y
• 5x + 7y
• 7xy + 1xy

Add or Subtract to Simplify:
(4x²+ x) - (x²+ 2x)

• 3x² - x
• 4x² + 2x
• 3x² + 3x
• 3x² + 2x

Find the difference. 
(3- 2x + 2x²) - (4x -5 +3x²)

• x_² + 6x + 8
• 2x² + 5x - 7
• -x² -6x + 8
• -2x² + 11x - 4

Add: (3x - 2) + (3x² + 6x)

• 3x² + 9x - 2
• 6x² + 4x
• 3x² + 3x - 2
• 6x² + 6x - 2

(2n + 2)(6n + 1)

• 12n + 2
• 12n² + 2
• 12n² + 12n + 2
• 12n² + 14n + 2
